OBJECTIVE. It has been hypothesized that secretory deficiencies of
growth hormone may play a pathophysiological role in
fibromyalgia (FM). Our objective was thus to evaluate the
secretion of growth hormone in FM.

RESULTS. Sleep was
significantly more disturbed in the patients than the
controls. We found no significant differences in the urinary
excretion of growth hormone and serum levels of IGF-I between
patients with FM and healthy controls.

CONCLUSION. Major
secretory deficiencies were not documented. However, the power
of our study does not allow us to discard the role of minor
secretory deficiencies of human growth hormone in FM.
